A software contractor invoice is designed to be used by independent software developers and engineers for the purpose of collecting payment by start-ups or established companies for the contracted coding services provided. Developers charge for their services on an hourly basis with different hourly rates set depending on the programming language(s) that are required for the job.

Software developers are the brains behind the programs and applications used today. They plan, structure, and organize how a program or application will run by both discussing the needs of the client and by gauging the level of performance and security that will need to be built into the software. The common tasks of a software developer include:

Meet with clients and team members to discuss the problem(s) that need to be solved;

Pre-arrange how the pieces of the project will fit together;

Create a roadmap and instructions for a team of developers and programmers to follow;

Develop new software using a variety of programming languages and software;

Conduct benchmarking and testing to identify security or performance flaws; and

Identify potential upgrades and create instructions on maintaining software into the future.

Those looking to become a software developer should have a knack for problem-solving, a penchant for detail, a healthy dose of determination, and a drive to continue honing their programming skills. Formal education is mandatory for many of the jobs that can be applied-to. While developers can strike their own path and learn to code on their own – many companies and freelancing platforms only accept those that have been formally trained in a university setting. Majors that serve as a stepping stone to becoming a software developer include computer science, software engineering, and mathematics.

A programmer will often base their hourly rates upon the size of the job (also called the “scope”), the service they are being hired to complete, and their years of experience. On average, independent software developers charge anywhere from $50 to $300 per hour. According to UpWork, the following are the average rates charged based upon differing development types:

Software developers earn an above-average salary due to the difficulty of their work and the need for qualified developers only increasing in the workplace. The following is the average salary and hourly rates for developers working in the United States:
